comment Quantifier problems of equations in physics
@Brian, your question assumes implicitly that formulating the $E=mC^2$ should follow a mathematical format. You might want to make this into a question and make it explicit.

@Gerry, I agree that the question should be rewritten to conform to parameters here.

@Brian, you might want to clarify your question to meet guidelines. Right now it is not entirely clear what you are asking. See also my comment in response to Gerry.

comment Quantifier problems of equations in physics
@Gerry, he is asking why the quantifier conventions in mathematics and physics are different. Seems like a legitimate soft-question here.

@Brian, I am not sure why you voted to close your own question.

Sorry, you must be alluding to one of the comments above but I haven't read everything in detail. At any rate mathematical physics is very much part of mathematics, and we are lucky to have many top people working in both fields.

comment Notation for the set of all arguments corresponding to local minima.
That's true, but to find the minima you are going to have to start by finding the extrema anyway :-) On the other hand, if you are dealing with nonsmooth functions then my notation does not help too much.

But you did already in your question. What are you not sure how to write down?

comment Euler's Formula, Square root
Are you trying to express $i$ itself in the form $e^{i\theta}$?

revised Is there an adjective appropriate for describing mathematical terminology that you feel needs to be phased out?

Hopf-Rinow is true provided there are finitely many connected components.

comment Question about index notation on partial derivatives.
Looks like it's a misprint and it should be $x'^\mu$.
